Halfspace Simulation of Rough Surface Contact in Metal Forming

Hauer, F. ; Willner, K. ;

Full Article:

Friction has a significant influence on the product properties and tool lifetime in metal forming processes. Therefore it frequently limits the possibilities in the product design. A detailed understanding of friction is necessary to overcome this obstacle. Numerical simulations as well as experimental work are required to gain more knowledge on the processes in the contact interface. The multiscale character of surface roughness makes a fine discretisation necessary, which leads to a huge numerical effort. Consequently alternative approaches to a Finite-Element model are of great interest. Halfspace models have shown their potential in elastic calculations and in plastic simulations with a simplified modelling of plastic deformation. In order to advance the modelling of rough contact in metal forming an enhanced plasticity model is applied within the halfspace framework.
